16 GB DDR4-2666 ECC RDIMM

This 16 GB DDR4-2666 ECC registered DIMM is built for Dell PowerEdge R440 servers. It runs at 1.20 V with CL19 latency and a 2Rx8 organisation across 288 pins. The module adds capacity to systems that require registered, error-correcting memory for stable operation.

Suited for R440 capacity upgrades.

Administrators expanding a PowerEdge R440 will find the registered ECC design matches the server's memory controller. Workstations or desktops that accept only unbuffered non-ECC DIMMs cannot use this module, so buyers needing standard desktop memory should look elsewhere.

Registered ECC is the deciding specification

The single specification that determines fit is the registered ECC RDIMM format; only systems designed for registered error-correcting DDR4-2666 modules can accept this part. Verify the server manual calls for registered ECC before purchasing.

Questions about this item

Will this 16GB DDR4 2666 ECC RDIMM run with the existing 2666 MHz modules already in my PowerEdge R440?

Yes, the module matches DDR4 2666 (PC4-21300) speed, 1.20 V voltage, CL19 latency and 2Rx8 rank, so it will operate alongside identical-spec sticks without down-clocking.

How can I confirm the new memory is recognised and ECC is active after installing it in the R440?

Enter the BIOS or iDRAC on the PowerEdge R440; the system should show 16 GB per module at 2666 MT/s with ECC enabled and no correctable-error alerts.

Does the package include only the 288-pin RDIMM or are any tools or cables supplied?

The box contains the single 16 GB DDR4 2666 ECC RDIMM (part MR21300-628K1); no tools, cables or additional hardware are included.
